Terra-Gen and Mortenson have officially activated the Edwards & Sanborn Solar + Energy Storage project, marking a significant milestone as the largest solar-plus-storage venture in the United States.

Mortenson, serving as the engineering, procurement, and construction (EPC) contractor, played a crucial role in bringing this renewable energy powerhouse to fruition.

Encompassing a sprawling 4,600 acres, the project boasts 1.9 million US-made First Solar panels, contributing to an impressive capacity of 875 MWdc solar. Additionally, the energy storage component is a substantial 3.3 GWh, with a remarkable 1.3 GW interconnection capacity.

Situated in Kern County, California, and partially located on the Edwards Air Force Base, the Edwards & Sanborn project emerges as a key player in the state's push towards sustainable energy.

California's grid is expected to receive an ample supply of electricity, equivalent to powering approximately 238,000 homes, resulting in an estimated annual abatement of 320,000 tons of carbon dioxide emissions.

The project's energy storage infrastructure is comprised of batteries from LG Chem, Samsung, and BYD. The engineering feat involved the installation of 98 miles of MV Wire, over 361 miles of DC wiring, and a staggering 120,720 batteries.

Notably, Edwards & Sanborn represents the largest public-private collaboration in US Department of Defense history.
